French: from the Late Latin name Renata, feminine of Renatus ‘reborn’, used by early Christians as a baptismal name celebrating spiritual rebirth in Christ. The name is also used in the English-speaking world, often without the accent and in a highly Anglicized pronunciation (compare Reenie).
French (Sévère): from the personal name Sévère, Latin Severus, meaning ‘harsh, austere’. Severus was the name of several Roman Emperors, including Alexander Severus (died 235), born in Syria, who was noted for his virtuous and studious character and his tolerance towards Christians. The personal name enjoyed some popularity among early Christians.
